SPECIFICATION forming part of Letters Patent No. 381,995, dated May 1,1888.

Application filed August 30, 1887.

To all whom it may concern:

Be it known that we, ZAOHARY T. FRENCH and WILLIAM C. MEYER, both ofBoston, county of Suffolk, and State of Massachusetts, have invented anImprovement in Machines for Cutting and Embossing Button-Holes, of whichthe following description, in Connection with the accompanying drawings,is a specification, like letters on the drawings repre senting likeparts.

This invention has for its object to improve the construction of thatclass of machines wherein a button-piece or fly may be both out to forma button-hole and embossed about the edge of the hole to representstitching, as in United States Patent No. 364,148, dated May 31,1887,and as herein shown the said buttonpiece is also scalloped at itsedge.

In accordance with our invention the material to be out and embossed andscalloped is laid within a strip carrier, preferably made as anarc-shaped piece of metal, having an opening therein of the form andsize of the but ton-piece. This strip -carrier, held between guides, isengaged and moved intermittingly by a novel feeding finger or device tothus place the button-piece in position to be acted upon by the cuttingand scalloping tool, and thereafter by the embossing-tool, as will bedescribed.

' The particular features in which our invention consists will bepointed out in the claims at the endof this specification.

Figure 1 is a front elevation of a machine embodying our invention. Fig.2 is an under side view of one of the tools employed to cut thebutton-hole stitch and scallop the edge of the button-piece. Fig.3 is anunder side view of the tool used to emboss the edge of the button-holeslit and also the materialjust within the scalloped edge of thebutton-piece. Figs. 4 and 5 represent details of the machine to bereferred to. Fig. 6 is avertical section of the machine shown in Fig. 1in the line .10. Fig. 7 is a top or plan view. Fig. 8 is a righthandside view of the machine shown in Fig. 1.

Serial No.248,217. (No model.)

Fig. 12 shows the strip-carrier and top of the oscillating bed under it,together with the guides, partially shown in Fig. 9, and a stripper, tobe described. Fig. 13 is a partial section in the line as, Fig. 1. Fig.14 is a sectional detail below the dotted line 00, Fig. 1, chiefly toshow the feeding devices and co-opcrating parts. Fig. 15 is a section ofFig. 13 in the line x looking to the left. Fig. 16 is a partial sectionin the line y, Fig. 1. Fig.

17 represents a button-piece or fly, a part of which is simply cut andscalloped, while another part is embossed.

The frame-work A, of proper shape to hold the working parts, has apower-shaft, A, provided with a beltreceiving wheel, A and a pinion, A',which engages a toothed gear, A*, fast on a cam shaft, A, provided witha double throw cam, A ,and a cam-hub, A The doublethrow cam A at eachrotation of the shaft A, meets twice the anti-friction roll a, mountedin a yoke, A, pivoted on a stud, a, (see full and dotted lines, Fig. 7,and dotted lines only, Fig. 6,) the said yoke being pivoted in therecessed or slotted end of the arm B, attached to a rock-shaft, B, thesaid yoke being made adjustable by a screw, 13*, so that the arm 3 mayhave its throw varied, as may be desired. The rock-shaft B has a secondarm, B*,which is extended forward to the front part of the machine.

The face-plate B is secured firmly to the frame-work by bolts B, and tothe face-plate v is attached, by screws B caps B, of suitable shape toreceive between them and serve as caps for the slide-bar B, slotted nearits upper end for the entrance of the arm 13* of the rocksha-ft B, sothat the said rock-shaft and arm effect the reciprocations of the saidslide-bar. The upper end of the slide-bar B has attached to it, byscrews B, a cross-bar, B through which are extended loosely two studs,B, erected upon the face-plate and surrounded below the said cross barwith strong spiral springs B", the said springs normally acting to liftthe slide bar.

The slot in the slide-bar (see Fig. 1) is of sufficient size to receivenot only the arm 13* of the rock'shaft B, but also a tongue, 0, to bedescribed, the latter having combined with it mechanism, to bedescribed, whereby it may be moved horizontally at the proper time tostop or start the movement of the slide-bar, the latter standing stillso long as the tongue is retracted into the position shown in Fig. 6, asin such position the downturned toe (shown chiefly by dotted lines inFig. 6) of the arm 13*, moved continuously, descends past the end of thetongue 0 and does not depress the slidebar; but when the operatordesires to depress IO the slide-bar in unison with the arm 13*, then thetongue 0 is thrown forward, so that its enlarged end is interposed inthe path of the toe of the arm B so that the latter strikes the tongue,it lying upon the bottom of the slot in the slidebar and depressing it.

The slide-bar B has a stud, D, which serves as a pivot for theoscillating tool carrier D, to which are secured, as herein shown, thebutton hole cutting and scalloping tool D and the 2o button-hole andedge-embossing tool D, under side views of which are shown,respectively, in Figs. 2 and 3. The tool D has a curved blade, a and aslit-cutter, a. The tool D has two embossing-surfaces, a and a, theformer to emboss the scalloped edge of the button-piece, and the latterto emboss the material in the imitation of stitching about the edge ofthe button-hole slit.

The carrier D at its rear side has a stud, a (see dotted lines, Fig. 6,)upon which is mounted a loose slide block, a, the said slide-blockentering between two like lugs or ears of a slide, a, secured by asuitable screw, a, to a rod, D adapted to slide freely horizontally inbearings D, forming part of the frame-work. The slide-rod D has attachedto it at one end a cross-head, D, which at its other end is secured to aslide'rod, E. The cross-head D has a bolt or stud, D over which isfitted one end of a lever, D having its fulcrum at D, the opposite endof the said lever having a roller or other stud, D", which enters aoam-gr0ove in the hub A, thelatter in its rotation moving the lever Dand causing the slide-rods D and E to be reciprocated horizontally inthe same direction.

In the reciprocation of the slide-rod D the ears of the slide a, actingupon the slide-bloek a", spring the tool-carrier on its pivot D, so thatat one reciprocation of the slide-bar B the scallop and slit-cuttingtool D is placed in I position to descend upon the button-piece at thenext descent of the said slide-bar B The embossing-t0ol D, by a changeof position of the tool-carrier D, is left in position to descend uponand emboss the button-piece, the two descents of the slide-bar B beingmade as herein provided for during each complete ro tation of the shaftA.

The slide-rodE has bolted or clamped to it by a screw, 13*, a block, E,provided with a slot, which receives in it arolleror other stud, E, (seeFig. 1,) secured to a crank or arm, E, clamped upon the lower end of theshank E of an oscillating bed, E to which is secured the scallop andslit die B, (see Fig. 7,) which consists, as herein shown, of smoothbrass or ting and scalloping tool D when it is to descend and to placethe embossing-die E under the embossing-tool D when it is in position todescend upon the button-piece.

The piece of material, G, to be cut and embossed is placed in the openspace between the side walls of the strip carrier H, the said piece orblank corresponding externally with the shape of the space in thestrip-carrier.

Fig. 17 shows the piece of material as partially scalloped and slit, anda little fartherou the edges of the scallop and the edges of the slitare shown embossed.

The strip-carrier H, herein shown as an arc-shaped piece of metal, iscut out to form a space corresponding in shape with the buttonpiece.This strip'carrier is adapted to be moved step by step or intermittinglyover a bed-plate, H, by a feeding device, which will be described. Thestrip-carrier H, at its up- .per and lower sides, has suitable fingers,as b, which aid in retaining the button-piece within the recess of thecarrier. The convexed edge of the strip-carrier is in practice pressedagainst three rolls, two of which are marked 1) b while the third rollis marked 1). (See Figs. 9 and 12.) The rolls b are mounted uponstuds 1) of sliding fingers b, properly bolted to a cross-head, b, thesaid cross-head being loosely mouutedupon the shank of a finger, b,which is rigidly but adjustably held,'as will be described. The finger bis extended through a spiral or other spring, as I), located between thecross-head b and the lug b, bolted to the frame-work, the rear end ofthe said finger receiving upon it a thumb or other nut, the rotation ofwhich enables the operator to adjust the finger b longitudinally orlaterally away from or toward the strip-carrier H. The finger b, itcarrying the roll b, is splined, as at b", to receive asuitable keyattached to the cross-head I). The finger b next the crosshead b, hassecured to it by a suitable screw a collar, b, the collar limiting theforward motion of the cross-head b, and consequently of the rolls 1).The threaded nut I) engages the threaded rear end of the finger b, sothat the rotation of the said nut enables the said finger to be adjustedwith the fingers according to the distance it is desired that the outerend of the button-hole shall be started back from the convexed edge ofthe strip-carrier.

The fingers b and b, with their attached rolls, constitute an edge-guidefor the stripcarrier H, and the spring 1) permits the fingers b to slideindependently of the finger I), thus enabling the rolls b andb to adaptthemselves properly to the convexed edge of the strip-carrier H nomatter what may be its curvature, the said edge of the strip-carrierbeing kept pressed against the said guide by lIO means of a roll, b",(see Figs. 7, 8, and 12,) mounted on a stud of a slide-bar, b, heldloosely in a guide, I), attached by suitable screws, as in Fig. 7, tothe bed H. This slidebar b is normally held forward with its rollagainstthe convexed edge of the strip carrier H by a spiral spring, a,(see Figs. 6 and 8,) attached to the bed H, and also to a stud of thesaid slide-bar, a handlever, as c, pivoted at and slotted'to embrace apin or stud, c, of the slide-bar b, enabling the operator to move thesaid bar away from thesaid edgegage whenever it is desired to remove orinsert a strip-carrier. The guide b has secured to it a stripper, b(shown best in Fig. 12,)

which in practice is extended across the stripcarrier and the blanktherein to prevent the said blank from being lifted from thestripcarrier as the cutting or embossing tool rises after havingperformed its work. The surface of the rotating table is sunk into thetop of the bed H so that the face of the table is flush with the face ofthe bed.

The strip-carrier H is provided at its convexed edge (see Fig. 12) withaseries of holes, as 2, one for each button-hole slit to be out, eachhole being substantially in line with the button-hole, slit to be out.These holes are entered intermittingly by a feeding device,.

(shown in Fig. land in detail, Fig. 14, as a finger, c,)it having ateat, 0*, (see Fig. 1,) to enter the said holes 2, one after the other.The finger 0* is pivoted at 0 between ears of a block, 0", having at itsrear side two studs, 0 and c, the said studs entering, respectively,holes 0 and a" (see Fig. 5) in a slide, '0, arranged to be reciprocatedin guides 0 (See Fig. 8.) The stud 0, extended through the hole c,hasapplied to it anut, c", the said stud serving as the pivotal point forthe block 0".

The stud 0 preferably made as a rollerstud, as shown best in Fig. 4., isarranged to travel upon a track, 0 slotted, as at a, to receive bolts,as 0 (see Fig. 6,) so that the said track may be raised and lowered, forthe purposes to be described. The track 0 (see Fig. 6) is jointed at itsupper end by a suitable pin to an elbow-lever, 0 having its fulcrum at0'', andjoined by a link, as 0', to a stud, c, secured to anelbow-leve'ne, having its fulcrum at c.

The feeding device is reciprocated constantly, even when the slide-bar Bis at rest, and at such times as it is desired that the feed shouldstop. When the slide-bar is at rest, the end of the tongue 0, as beforedescribed, is thrown backward, as in Fig. 6, its stud a being in theslot 0' of the elbow-lever 0", and in such position the track 0" is heldelevated, so that the teat of the feeding-finger cannot enter the holes2; but whenever "the tongue 0 is thrown forward the upper end of thelever 0 is thrown forward, carrying with it the tongue 0. Then the track0 is so lowered as to permit the feeding-finger c to descend and feedthe strip-carrier H intermittingly. The lever c has connected to itslower end a rod,

6, which at its lower end will in practice be connected with a suitabletreadle under the control of the foot of the operator, the latterdepressing the said treadle and throwing forward the tongue 0 wheneverit is desired to force downward the slide-bar B. This lever 0 hasjointedloosely to it by a stud, e, a link, 0 which atits upper end is looselyjointed by a stud, 6 to a pawl-raising link. e, having a stud, 6 uponwhich rests the end oftwo pawls e e, (see Fig. 7,) the pawl 6 beingpivoted at e on a lug or ear of the hub, secured to the rock-shaft B bya set-screw, B. The pawl e is pivoted upon the frame-work of the machineby a stud in line with the stud e and therefore not visible on thedrawings. The end of the link e is pivoted at e to the framework.

The hub has suitably secured to it a hook,

-7", which at times engages the hooked end of an elbow-shaped catch, f,pivoted at f the opposite end of the said elbow-catch having pivotedtoit a link, f (Shown by dotted lines in Fig. 6. See also Fig. 13.) Thedescent of the right-hand end of the leverf (see Fig. 13) is arrested byastop, f aspring,f", connecting the lever-f, and the catch f normallydrawing the catch f toward the hook; but a pin, f arranged near thecatch, prevents the upper end of the catch from passing too far towardthe hub. The link f at its lower end has a stud, h, and the rear side ofthe toolcarrier D has extended from it through a slot :in the slide B astud, h, (see dotted lines,

Fig. 1,) the said stud h passing in far enough to reach and act upon thestud h at certain times. The-shankof the tongue 0 has a projection, asit, (see Figs. 7 and 13,) with which the leverf acts to form a lockingdevice to retain the tongue 0 backward, so that the operator cannotstart the machine when the embossing-tool D is immediately in positionto descend upon the button-piece, the object being to always first cutthe button-hole slit and then during the same rotation of the shaft Apermit the tool D to descend and einboss the edge of the button-hole.

In operation the hub is rocked by the cams A", and at each oscillationthe hook f passes below the shoulder of the catchf; but should theembossing-tool D be in position to descend upon the material whentheoperator by the treadle moves the lever c to start the machine, thenthe pin h,acting on the pin hof the linkf, holds the catch f out ofrange of the hookf, and also holds the opposite end of the leverfagainst the projection h. The framework Ahas upon it a stud, m, having acollar, m. (See Fig. 11.) Between its collar m and the nut m the studreceives upon it loosely a beveled edge wheel, m the said wheel beingslotted, as at m, .to receive a bolt, as 117?, by which to secure thesaid wheel m to a ratchet-wheel, m

At the rear side of the ratchet-wheel is a coiled spring, m, theupper-end of which is attached to a pin extending from the ratchet- IOCwheel, while the inner end ofthe spring is atl tachcd to a stud extendedfrom the collar m 1 This ratchet-wheel is rotated l of the stud m.intermittingly by the pawl e", and retrograde motion is prevented by thepawl e. The lower end of the elbow-lever c is normally kept ele vated bythe spiral spring a. The lever has pivoted upon it at n a catch, a,which is normally acted upon by a spring, as a, the latter causing thehook to engage the edge of the beveled-edge wheel on when the lever 0 isthrown forward by the depression of the treadle. The movement of thelever 0', as described, to engage the hook at with the beveled-edgewheel depresses the link a and stud e on the link 0, so that the pawl cengages the teeth of the ratchet-wheel and rotates it on the stud m ateach backward movement of the hub of the rocker-shaft. The rotation ofthis ratchet-wheel is continued, and the slidebar B is depressed and thetool carrier is shifted thereon to first cause the button-hole andscalloping tool to operate and then the embossing-tool to operateintermittingly until in the rotation of the ratchet-wheel the slottedportion a (see Fig. of the beveled-edge wheel at rises opposite thecatch a when the spring n immediately acts to throw back the upper end'of the lever c and draw back with it the tongue 0 and stop thereciprocation oi the slide 13. The slot at in the bevelededge wheelpermits it to be adjusted with relation to the ratchet-wheel, so thatthe machine will be stopped sooner or later, that depending upon thenumber of button-hole slits to be cut in the button-piece then placed inthe carrier. The cross-bar D (see Fig. 1) has attached to it by a screw,0, a connecting-rod, 0, which at its opposite end is joined by ascrew-stud, 0, to a disk, 0, (see also Fig. 16,) having a central studat its rear side, which enters a hear ing, as 0, attached to theframework.

The disk 0 has a slot, 0", in whichis placed a radially-adjustablebearing, 0", the said bearing receiving in it the shank of a threadedclamp-nut, o, the said nut having a clamp screw, 0 and fitting athreaded sleeve, 0", mounted loosely upon a connecting-rod,p, between acollar, 22, and a nut, 23, fast on the said rod. The opposite end of therod p (see Fig. 14) is jointed to the block 0, (shown separately in Fig.5,) the rotation of the threaded sleeve in the said clampingnut drawingthe block'c more or less to the right or left to thereby adjust thefeeding device mounted on the said block in such position that thefeeding-finger may move the strip carrier to leave it in just the properposition, the adjustment of the bearingnut in the slot varying thelength of the feeding-stroke. The feeding-finger c has at its rear endan adjusting device, (shown as a screw, 93) the inner end of which abutsagainst the block 0, a spring, r, normally keeping the screw against thesaid block, rotation of the screw moving the feeding-finger toward orfrom the rod p, so as to enable the teat 0* to correctly enter the holes2 of the strip-carrier H.

\Ve do not desire to limit our invention to the exact form of lockingmechanism between the tool-carrier and the tongue C to prevent it frombeing pushed forward to reciprocate the slide B when the embossing-toolD is in position to descend upon the button-piece; and so, also, we donot desire to limit our invention to the exact mechanism shown by whichto automatically withdraw the tongue 0 and stop the reciprocation of theslide-bar and the movement of the carrier H.
